Helbling did not hit Stamkos with an elbow, it was Stamkos that tried to hit Helbling along the boards and got himself and Helbling off balance and actually ran into Helblings elbow. There was no penalty called and the hit seemed like a nothing collision. If Stamkos gets concussions out of something like this he has to pay attention for the rest of his career otherwise he'll get problems.
